Database import from 1.10 into 1.9.16

Can anyone please tell me if it is possible to take a database from a 1.10.1 install and import it into a fresh 1.9.16 install? We are moving to a new server in the near future and would like to go back to 1.9.16 but don't want to lose out data from our current 1.10.1 build.

It is possible. But there is no mechanism made by osTicket to do so, so you would have to look at all of the mysql queries done during the upgrade process and reverse engineer them. If anyone has done it they have never posted here about it.
